The VR1 Semi-Automatic Precision Sniper Rifle (PSR) ismanufactured in USA by Vigilance Rifles, an independent gun-makingcompany. This rifle is one of the very few semi-automatic riflesproduced to fire specially designed powerful long range ammunition suchas .338 Lapua Magnum (8.7x69mm) and .408 Chey-tac (10.3x77mm). Theserounds generate muzzle energies ranging from about 6,500 Joules(.338LM) to 11,300 Joules (.408CT), and that is about 2 to 3 times moreenergy than is generated by the most common 7.62x51 NATO / .308 Winround, used in most semi-automatic sniper rifles today, and about 1/3to 2/3 of the muzzle energy generated by much bigger .50BMG round. Withsuchballistic characteristics, this rifle nicely fills the niche betweenlight, rapid-firing (semi-automatic) sniper rifles in 7.62mm caliber(which have limited capabilities against material targets, heavy bodyarmor and limited range) and heavy, powerful 12.7mm / .50 caliberanti-material rifles which have great destruction potential but usuallyare too big and heavy (average weight is 14 kg / 30lbs) for rapiddeployment and maneuver warfare. TheVR1 rifles also can be used by civilian shooters for long-range targetshooting and long-range / big game hunting (for this purpose, theextra-powerful big-game caliber .505 Gibbs is available for VR1). Withproper .338 or .408 caliber ammunitionmanufacturer claims accuracy of 1 MOA at 600 yards and maximumeffective range extends up to a mile (~1600 meters).
